Phase‐change random‐access memory relies on the reversible crystalline‐glassy phase
change in chalcogenide thin films. In this application, the speed of crystallization is critical for …

While polymorphism is prevalent in crystalline solids, polyamorphism draws increasing
interest in various types of amorphous solids. Recent studies suggested that supercooling of …

Phase‐change materials (PCMs) used in data storage devices have unique structural
features and transition properties by thermal heating. Pressure, as another important …

A striking anomaly in the viscosity of Te 85 Ge 15 alloys noted by Greer and coworkers from
the work of Neumann et al. is reminiscent of the equally striking comparison of liquid …

Layered transition-metal trichalcogenides have become one of the research frontiers as two-
dimensional magnets and candidate materials used for phase-change memory devices …

Using synchrotron X-ray scattering, we investigate liquid Ge 15 Te 85 spanning a wide
temperature range from near T g to the melt, and demonstrate that the density anomaly and …

The dynamic properties of liquid phase-change materials (PCMs), such as viscosity η and
the atomic self-diffusion coefficient D, play an essential role in the ultrafast phase switching …

Glass-transition temperatures (T g) and liquid fragilities are measured along a line of
constant Ge content in the system Ge-As-Te, and contrasted with the lack of glass-forming …

The temperature-dependent viscosity η (T) is measured for the equilibrium liquid of the
chalcogenide Ag–In–Sb–Te (AIST), the first time this has been reported for a material of …

Electronic phase‐change memory devices take advantage of the different resistivity of two
states, amorphous and crystalline, and the swift transitions between them in active phase …
